A Marathon man who did a year and a half in prison after threatening the lives of President Obama and former President George W. Bush was jailed again Sunday for allegedly possessing a gun when he’s not allowed to have one.

Raymond Geisel, 27, is charged with possession of a weapon by a convicted felon. He’s in the county jail with no bond allowed.

Becky Herrin, spokeswoman for the Monroe County Sheriff’s Office, said her agency received more than one tip that Geisel had a gun aboard the sailboat he lives on in Boot Key Harbor.
